Acer palmatum 'Okushimo' Japanese Maple

The Acer palmatum ‘Okushimo’ is a distinctive and unusual upright green Japanese Maple admired for its unique curled foliage and elegant vase-shaped form. The light green leaves feature margins that curl upward, creating a textured and architectural look unlike most other cultivars.

The name ‘Okushimo’ translates to “salt and pepper”, referencing the refined and intricate nature of its foliage. This historic Japanese cultivar is often underutilised, yet it offers exceptional landscape value. In autumn, the foliage transforms into beautiful shades ranging from bright yellow to deep orange, adding vibrant seasonal interest.

With its naturally narrow, upright growth habit, ‘Okushimo’ forms a graceful vase shape that remains elegant even at maturity. It works beautifully as a focal point specimen or when planted alongside contrasting Japanese Maple varieties.
